LUBRICATING COMPOUND,

SPECIFICATION forming part of Letters Patent N 0. 268,546, dated December 5, 1882.

Application filed July 25, 1882.

To all whom it may concern Be it known that I, JOHN E. SAWYER, a citizen ot' the United States, residing at Napa, in the county of Napa and State of California, have invented a new and useful Composition of Matter for Lubricating Purposes, of which the following is a specification.

' My composition consists of the following ingredients, combined in the'following proportions stated, to wit: tallow, sixteen (16) pounds; plumbago or black-lead, one (1) pound; fullers-earth,one-halflg) pound; soapstone or steatite, one-half pound; lard-oil, one (1) pint. The soapstone, p1umbago,and

fullers-earth are pulverized and the tallow melted, when the soapstone, plumbago, fullers-earth, and lard-oil are mixed with the tallow, and the whole passed through a grindingmill and thoroughly mixed and incorporated by grinding while the tallow is in a hot or melted state. By this means the composition V will always remain in alimpid or plastic state,

and will not cake or harden in the containingcan, and when applied to axles will remain a (No specimens.)

long time without a new application; and it will also prevent the heating of the axle to which it is applied.

I am aware that steatite or soapstone and black-lead or plumbago have heretofore been employed in lubricating compounds; but I am not aware that all of the ingredients of my compound,in the proportions stated, havebeen used together.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

The herein-described composition to be used as a lubricant, consisting of tallow, plumbago, soapstone, fuilers-earth, and lard'oil, mixed and compounded in the proportions stated.

In testimony that I claim the foregoing I have hereunto set my hand and seal this 26th day of June, 1882.
